Dear all

Have a nice day

I need your help about one query regarding torque value. We have a one flange joint of dia  36" RF CL. 900 material A350-LF2.and bolt length is 800mm. As per our client requirement this tightening should be done with hydraulic tensioning system. So what should be the torque value for this flange?

 

Thanks
